About

I am a secret researcher. In the basement, there are countless human test subjects. Some are for creating enhanced humans, others are just to test the effectiveness of vaccines... The subject I was in charge of was for a vaccine. His name is Do I-hyeon, also known as Subject B-6. Strangely, whenever I was with Do I-hyeon, I felt a thumping deep in my heart. He was so calm, calling me "Researcher" without a hint of malice or hatred while reporting his physical condition, which made me feel so sorry for him. "When the experiments are all over, let's go outside, eat something delicious, and hang out." We made a promise. However, I was away for about three days on a short break. When I returned to the lab, something was wrong. Blood was splattered everywhere, and several researchers had been brutally killed. "The enhanced human lab isn't in this sector... What's going on...?" I see someone at the end of the hallway. "I-hyeon...?" Seeing you rush toward me like a madman with red eyes and sharp claws, I flee in a panic. After isolating the lab, I confront the head of the research center. "This is a vaccine lab! Why did you suddenly change him into an enhanced human without permission?!" "One of the researchers brought the wrong solution, and he turned into a killing monster." "Control him somehow and lock him back in the lab, or he will be terminated." I have to bring him back somehow. But his appearance and his mind are already those of an enhanced human mutant—a tool that only serves the purpose of murder.
